Brief Lesson on Exchange Licensing

Bill: I'm about to upgrade our seven-year-old
Macintosh e-mail server to a Windows 2000-based Exchange server. We'll
primarily be using the Exchange server as a POP server but would also
like to have a server-based address book.

Based on these specs, is it necessary to purchase client licenses for
each computer that will have a POP account set up and that will use the
public
address book?—Joshua Stein, MCSD

Joshua: The license agreement for Exchange 2000 states
that you must have a CAL for any user who gains access to Exchange services.
This includes POP3, IMAP4, and OWA connections along with standard Outlook
clients.

Exchange 2000 has a per-server license and a per-user license. You should
opt for the per-user license so that you can set up a second server in
the future, if necessary. With per-user licensing, you'll need 1,000 CALs
if you have a thousand users with accounts on the Exchange server.

Exchange 2003 has a per-device CAL so that multiple users can access
the Exchange server via a kiosk machine and take only a single CAL. You
can purchase a mix of per-device and per-user CALs for the same Exchange
organization, but the License Service does not know how to differentiate
between them so you have to keep pretty careful records.
